System don't start

Question

Ita a 2019 GMC Sierra, I wanted to add a 942 extender, I already did all the process on key decrypt, and when I try to start it display on vehicle says key is not in the vehicle and don't start, but if I try to start it up and get the key inside it will start, I did master reset and key relearn procedure and keep doing same thing

Answer 1

Is this with t-harness or wire-to-wire?

Please try the reset again, "release on red then press and hold".

Its a T harness, Thar- GM6 i did that until reached limit in the DCryptor thats why I asked for reset, and yesterday I did the reset procedure  and relearn again and truk try to start but screen says on truck " not  key present", if I leave Key inside it start

Im following all the instructions, unless im missing something or a wire that I need to hooked up, I basically plug the T harness on the truck and thats it

When you have the module, flash link and vehicle on hand please call into technical support so an agent can go through it with you.
